Blackfordby is a small village in the northwesternmost corner of Leicestershire about 2 miles (3.2 km) to the northwest of Ashby-de-la-Zouch and 2 miles southeast of Swadlincote in central England. On some early maps, such as one dated 1587, the village is shown as "Blaugherby", hence the local name of "Blofferby".

For many years the population remained at about 500, mainly agricultural workers, until the advent of the "Pits & Pipeworks", i.e. coalmining and drainage tile works. It is still a fairly quiet, rural village, although the population has greatly expanded in recent years.

The parish of Blackfordby was split and merged into the urban districts of Ashby de la Zouch and Ashby Woulds in 1936.
